Specifications

Good to Know

HP 56 and HP 57 are a pair: the 56 goes in the black slot and the 57 in the color slot. They look similar to the newer HP 21 and HP 22, but the two families are not interchangeable — a 57 will be rejected by an HP 22 printer such as the OfficeJet 5600 series or DeskJet F4100 series.

Printing photos? You can swap the 56 out for an HP 58 Photo cartridge in most of these printers, then put the 56 back in for everyday text. Pair it with an HP 57 Tri-Color for color.

Frequently Asked Questions

Is there an HP 56XL?
No. HP never made an XL version of the 56 — the standard HP 56 is the only black cartridge for these printers.

Will the HP 56 work in my OfficeJet 5610 or DeskJet F4180?
Those printers are built for the HP 21 black and HP 22 color cartridges. For the DeskJet F-series and D-series, choose the HP 21 Black instead.

Are remanufactured cartridges as good as the original?
Yes, when they're done right. A remanufactured cartridge reuses the original manufacturer's shell, so it fits and works like the original. Ours are refilled, print-tested before shipping and covered by our 1-year 100% satisfaction guarantee.

Will using it void my printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, a printer maker can't void your warranty just because you used a non-original cartridge.

Will my printer show a message when I install it?
Some printers display a notice that a non-original or previously used cartridge is installed. Select OK or Continue and print as usual. If a cartridge isn't recognized, remove it, make sure any protective tape is off, wipe the contacts and reinstall it. See our guide to fixing a cartridge that isn't recognized, or contact us and we'll make it right.

How much will I save?
Remanufactured cartridges typically cost far less than OEM cartridges with the same yield. Estimate your yearly savings with our Printer Ink Cost Calculator.

When will my order ship?
Orders placed by 4 PM ET, Monday through Friday, ship the same business day from Long Island, NY. Standard USPS delivery takes 2–5 business days, and shipping is free on orders over $50. Expedited 1–2 day delivery is available at checkout.
